Bioscape All in One Pond Filter Riser Stem Fountain Heads

• Genuine fit for BIS670 and BIS671 – the same riser tube and nozzle set Bioscape supplies in the box on both models, since the two share an identical housing.
• Three interchangeable nozzles – change the spray pattern without buying a separate accessory kit.
• Riser tube included – replaces the stem itself, not just the nozzle heads, if the tube has cracked or the fit has gone loose.
• Push-fit onto the pump housing – no tools needed to swap it over.

This part fits the Bioscape All in One Submersible Pond Filter 2000LPH range only – both the standard BIS670 and the BIS671 with the built-in UV-C clarifier, since the two models use the same housing, riser and nozzle set. It does not fit Bioscape's hi-lift pond pumps (BIS580 to BIS583), the floating solar range, or any Bioscape aquarium filter. Check the model code printed on your unit's housing if you are not sure which pump you have.

Suitable for:

• Replacing a cracked, lost or worn riser tube or nozzle on a BIS670 or BIS671
• Changing the fountain spray pattern
• Fixing an uneven or spitting fountain caused by a partly blocked nozzle

Not suitable for:

• Any pump other than the BIS670 or BIS671 All in One filter
• Fixing low flow or a pump that hums but does not push water – that is usually the impeller, not the riser. See the All in One Pond Filter Impeller with Shaft
• Running a waterfall – this is a fountain riser, and maximum fountain height on both host models is 1.3 m

• Fitting: push the riser tube onto the pump outlet, choose a nozzle, and submerge. No sealant or tools required.
• Scale build-up: rinse the nozzles in pond water periodically if the spray pattern starts to drift – mineral scale narrows the opening over time in hard water areas.
• Storage: if you shut the pond down over winter, remove and store the riser and nozzles dry rather than leaving them submerged and idle.

• Bioscape All in One Pond Filter Transformer – the other part most exposed to weather on this unit.
• Bioscape All in One Pond Filter UV-C Globe 8W – for BIS671 owners due for the annual lamp change.
• Bioscape All in One Pond Filter Impeller with Shaft – if flow itself has dropped rather than just the fountain pattern.
• Bioscape All in One Submersible Pond Filter 2000LPH – the standard BIS670 host unit.

Does this fit the UV model as well as the standard one?

Yes. BIS670 and BIS671 use an identical housing, riser tube and nozzle set – the only difference between the two models is the UV-C lamp fitted to the BIS671. This part fits both.

My fountain sprays unevenly on one side – is this the fix?

Usually, yes. An uneven or spitting spray is almost always a partly blocked or worn nozzle rather than a failing pump. Try rinsing the existing nozzle first; if the pattern still will not even out, fit a new one.

Does this come with the pump?

No. This is the riser tube and nozzle set only, for owners who already have a BIS670 or BIS671 and need to replace a worn or missing part. The pump, filter sponges and ceramic media are not included.

Can I buy just the nozzles without the riser tube?

Bioscape sells this as one combined pack – riser tube and three nozzles together. There is no nozzles-only option in this part number.
